2021年4月7日 · The Ti 2p spectra are always split into two main peaks corresponding to Ti 2p 3/2 and Ti 2p 1/2. Any component fitted to a Ti 2p 3/2 peak should also be used to fit the Ti 2p 1/2 peak.

2023年2月1日 · Our XPS and TEM study documents how the surface chemistry can change during aging in air and that the Ti-F and Ti O surface termination groups are indicators for non-oxidized Ti 3 C 2 O x F x MXene. Moreover, we demonstrate that the storage of MXene at lower temperatures up to −20 °C can result in the stabilization of MXene platelets for ...

2022年8月15日 · Through first principles thinking it was possible to perform curve fittings of the F 1s, O 1s, Ti 2p, and C 1s XPS spectra from high quality Ti 3 C 2 T x MXene without using assumptions. Instead, a detailed understanding of the XPS spectra was deduced by guidance from seven pieces of well-established XPS knowledge.

2024年11月12日 · This study introduces a Ti 3 C 2 T x MXene@CuCo 2 O 4 (MCC) composite on a polyethylene (PE) separator to construct an ultrathin MXene@CuCo 2 O 4 /PE (MCCP) film. The MCCP functional separator can deliver superior LiPSs adsorption/catalysis capabilities via the MCC composite and regulate the Li + deposition through a conductive Ti 3 C 2 T x ...

本文分别利用HF溶液和LiF/HCl溶液刻蚀Ti 3 AlC 2 获得了Ti 3 C 2 T x 样品, 通过电子扫描显微镜(SEM)、X射线光电子能谱(XPS)和气敏特性分析, 研究了刻蚀剂对Ti 3 C 2 T x 材料结构和气敏性能的影响.

In our approach, we assign the Ti 2p peak at 455.1 eV to the C–Ti–O\O\O, and the peaks at 456.0, 457.0, 457.9, and 459.6 eV are assigned to C–Ti–O\O\F, C–Ti–O\F\F, C–Ti–F\F\F, and TiO2-xF2x, respectively. The first four represent possible Ti atom terminations; the …

5 天之前 · We also examined the Ti 2p peak of δ-MnO 2 @MXene (Figure 3d) and revealed a spectral profile consistent with that of pristine MXene, exhibiting the composite structure was successfully constructed. Among them, The Ti 2p 3/2 core-level spectrum exhibits four components: 456.1 eV assigned to Ti-C, 457.3 eV to Ti(II), and 458.3 eV to Ti-O.

Here, we report a facile method to delaminate MXene (Ti 3 C 2 T x) and prepare poly (vinylidene fluoride) (PVDF)/MXene composites by solution blending. Compared with neat PVDF, the PVDF...

The high-resolution Ti2p XPS spectra of f-graphene@Ti 3 C 2 -MXene nanohybrid (Fig. 2(d)) exhibit three prominent peaks that have been further deconvoluted into distinct components...

2024年5月7日 · 近日，天津大学材料学院金属功能材料研究团队通过气相蚀刻/官能团置换两步法制备了具有-P官能团的Ti3C2PBrx MXene并应用于超级电容器。 与-Br官能团的Ti3C2Br2 MXene相比，-P官能团的多层Ti3C2PBrx MXene的面电容性能得到提升。 在20 mV s-1的扫速下，由102 mF cm-2提高到了360 mF cm-2，并且在10000次循环后电容保持率没有降低。 充放电后的X射线光电子能谱学（XPS）测试表明，除了Ti的氧化还原反应提供的电容贡献外，增加的 …
